IMPROVED DlTCHiNG-MACHINE.

Specification forming part of Letters Patent No. 57,815, dated September4, 1866.

To all whom it may concern.-

Be it known that we, J AooB BALLARD, of New Antioch, Clinton county,Ohio, and THOMAS J. MAGEE, of Cincinnati, Hamilton county, Ohio, haveinvented a new and useful Ditching-Machine; and we do hereby declare thefollowing to be a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspecification.

This is an improvement in the class of implements designed forexcavating open ditches.

Figure 1 is a perspective view of a machine embodying our invention.Fig. 2 is a side elevation of the sliding mold-board. Fig. 3 representsthe sliding mold-board detached.

Projecting rigidly downward and forward from a suitable beam, A, is asheath, B, armed at bottom with a horizontal share, 0, and in front witha guide-plate, D, which leads from the share upward and rearward in themanner shown.

E is a bracket projecting from the furrow side of the beam, andcontaining a stout rung or bolt for the attachment of a cord or chainconnected with a Windlass or other motor.

The share is braced firmly to the beam by means of two knives orcolters, of which the colter Gr extends from the land side of the shareobliquely forward and upward to the beam, and the colter H extends fromthe discharge side of the share vertically, or nearly vertically, upwardto the bracket E.

Attached to the delivery side of the beam, so as to be parallel with theguide-plate D, is an upper guide, I.

The mold-board J is made capable of being slid up or down along thesheath, and is confined to its proper path in the act of adjustment bymeans of the guides D and I. The mold-board is formed with an upper andrear end projecting wing, J, for the proper turning of the furrow-slice,and a lower wing, J, for the delivery of the slice on the side of theexcavation.

The adjustment of the mold-board is effected by means of a pinion, K,gearing in a rack, L, upon the mold-board.

Hinged at M to the rear end of the beam is a handle, N, whose lower endcarries a wheel, 0, which runs in the bottom of the excavation.

P is an adjustable brace, which, in connection with a pin, 22, andperforation (t, secures the handle to its proper position.

Q is a rod, which, extending upward and rearward from the slidingmoldboard. and having a series of perforations, q, is secured to thehandle N by means of a pin, It, so as to hold the mold-board to anydesired adj ustment.

The forward end of the beam A passes between the two cheeks S of atruck, T, and is held to any desired vertical adjustment by means of ascrew, U, which engages in a crotch, V, which projects from the end ofthe beam.

A platform, t, upon the truck enables the operator to travel with themachine, and, with his hand on the screw, to adjust the machine to aless or greater pitch, so as to secure a uniform grade for the bottom ofthe ditch. To assist him in this adjustment, a curved.spirit-clinometer, W, is let into the top of the beam, a vernier, X,alongside of it indicating diiferent ascending and descending grades.

It is obvious aditch of any desired depth may be struck by repeatedthrusts of the implement, the sliding mold-board being, of course,adjusted higher at every thrust.

When it is desired to run the machine out of the ground, the handle isunbraced from the beam and allowed'to assume the position indicated bydotted lines in Fig. 2.

A series of perforations, a, in the beam enables the handle to be setmore or less forward, so as to change the elevation of the reai or ditchwheel 0.

We claim herein as new and of our'inveir tion-- 1. The arrangement ofsliding mold-board J, lower and upper guides, D and I, elevatingmechanism K L, and adjustable brace P, or their mechanical equivalents,substantially as set forth.

2. In the described combination, the beam A, sloping sheath B, share 0,and the oolters In testimony of which invention We here- G and H, as andfor the purpose set forth. unto set our hands.

3. The olinometer attachment W X, in 00111- JACOB BALLARD. bination witha suprmrting-truok,T, and regu- T. J. MAGEE. lating-sorew U, for thepurpose explained. Witnesses:
